Question by techcrab · Apr 27, 2014 at 05:24 PM · c#guiinput

Inputing an Equation

I want to have it so that the user enters an equation into a GUI text box. Then the program takes the string equation and graphs the equation.

I already know how to graph the equation and creating a text box to gain the string input but I'm having trouble taking the string equation that the user imputed and then changing that to something I can work with. I would like to have the program be made in C#.

Depending on the equations you that you wish to support this could be complex. NCalc is an open source c# mathematical expressions evaluator, you may find it a handy reference or try to use it as a back end?

This is a non-Unity design question, and it is beyond the scope of a Unity Answers question. I'd start by Googling, "code parse formula." This link from that search seems to be a good starting point:

You're basically asking how to build a parser, as robertbu has said. It's a complicated topic, and if you want to get it to work well, you'll need to do a lot of studying.
